From 436d34b36202ef724778ded1e9cb10f8c37b32bc Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Wed, 2 Apr 2008 17:28:46 +0900 Subject: [PATCH] libata: uninline atapi_cmd_type() Uninline atapi_cmd_type(). It doesn't really have to be inline and more case will be added which need to access unexported libata variable.
